Nampa or nanpa (both spellings are correct because of the way the 'n' character works in Japanese) is a Japanese term meaning the act of meeting and seducing women.

To put it in American terms, to "do nampa" is to "pick up women." So, if you have ever approached a stranger with the intention of establishing a romantic relationship of some kind (successfully or not), you have done nampa. Being introduced to a girl through a friend is not nampa.

However, in other contexts the word nampa may refer to the practice of meeting women by way of a popular Japanese courtship procedure, wherein young men stand at lively public areas and approach passing women in rapid succession until one agrees to an instant date (to a karaoke bar, for instance).

A term used to reference cannabis/marijuana/weed.

Japanese slang meaning to chase or hit on girls.

Nampa is a high crime and gang affiliated area in Idaho
